Explanation:
- Mechanical weathering involves the breakdown of the rocks into small pieces by the external support such as pressure whereas Chemical weathering involves the breakdown of the rocks takes place by the chemical process.
- Mechanical weathering is a physical change that is caused by the movement of wind and water whereas chemical weathering takes place when the chemicals present in the air or water get mixed with minerals or rocks.
- Mechanical weathering involves:
Abrasion, freezing, thawing, exfoliation.
- Whereas Chemical weathering involves:
dissolution, oxidation, carbonation, hydrolysis.
Answer:
The speed of an object is defined as the total distance covered divided by total time taken. The velocity of an object is defined as the total displacement divided by total time taken.
Explanation:
Answer:
Wetlands are places which contain more moisture content than the arid or dry land. It is believed that the wet region have less strength . As we all know anything which is in contact with water have lesser strength due to water molecules harm the chemical bonding in the object.
Ancient times house construction was done using natural rocks and stones and which reacted using physical bond hence the ancient people were successful as it used physical reaction and hence its strength was not affected by the moister. Present day homes are built using chemical bonds which told two layers adhere hence moisture affect its strength and binding.
Answer:
As the region is deforested, the topography, gravity, soil permeability and terrain slope will control the runoff, as well as the intensity of the rain.
Explanation:
Runoff occurs when water flows over a soil that is saturated, that is, soaked. What controls the runoff efficiently is the native vegetation of the place, however, when this area is cleared, the soil is completely at the mercy of saturation, causing the runoff to be controlled by topography, gravity, permeability of the soil and the slope of the terrain, as well as the intensity of the rain.
